Site-specific methylation: effect on DNA modification methyltransferases and restriction endonucleases.
We present in Table I an updated list of the sensitivities of over 240 restriction endonucleases to the site-specific DNA modifications '14C, n-6C, h1"5C, and m6A, four modifications that are common in DNA prokaryotes, eukaryotes, and their viruses (Mc2,Mc5,Mc8,Mcl 1 ,Ne3,Ne4). Table II is a list of over 130 characterized DNA methyltransferases. A detailed list of cloned restrictionmodification...
متن کاملEffect of site-specific methylation on restriction endonucleases and DNA modification methyltransferases
Restriction endonucleases have site-specific interactions with DNA that can often be inhibited by site-specific DNA methylation and other site-specific DNA modifications. However, such inhibition cannot generally be predicted. The empirically acquired data on these effects are tabulated for over 320 restriction endonucleases. In addition, a table of known site-specific DNA modification methyltr...
متن کاملCreating highly specific nucleases by fusion of active restriction endonucleases and catalytically inactive homing endonucleases
Zinc-finger nucleases and TALE nucleases are produced by combining a specific DNA-binding module and a non-specific DNA-cleavage module, resulting in nucleases able to cleave DNA at a unique sequence. Here a new approach for creating highly specific nucleases was pursued by fusing a catalytically inactive variant of the homing endonuclease I-SceI, as DNA binding-module, to the type IIP restrict...
متن کاملCharacterization of the 5-hydroxymethylcytosine-specific DNA restriction endonucleases
In T4 bacteriophage, 5-hydroxymethylcytosine (5hmC) is incorporated into DNA during replication. In response, bacteria may have developed modification-dependent type IV restriction enzymes to defend the cell from T4-like infection. PvuRts1I was the first identified restriction enzyme to exhibit specificity toward hmC over 5-methylcytosine (5mC) and cytosine. By using PvuRts1I as the original me...
متن کاملReaction kinetics of some important site-specific endonucleases
Reaction kinetics of the site-specific endonucleases BamHI, BgIII, C1aI, EcoRI, HpaII, PstI, SaII, SmaI, and XorII were investigated employing some frequently used substrates. Six of these enzymes could be analyzed under steady-state conditions. Kinetic data were obtained from progress curves applying an integrated Michaelis-Menten equation. KM ranged from 4 x 10(-9) M to 4 x 10(-11) M. Activit...
